declarations (and not function pointers). This is consistent with GCC. Accepting
this attribute on function pointers means that the attribute should be treated
as a type qualifier, which apparently is not what GCC does. We obviously can
change this later should we desire to enhance the 'malloc' attribute in this
way.
